Context-based search for a data store related to a graph node

ABSTRACT

A graph database storage system contains a graph database that has multiple graph nodes. A first pointer points from a particular graph node to a particular synthetic context event node in a synthetic context event database. A second pointer points from the particular synthetic context event node in the synthetic context event database to a particular data store in a data structure, such that the first pointer and the second pointer associate the particular data store with the particular entity represented in the graph database via the particular synthetic context event node.

BACKGROUND

The present disclosure relates to the field of computers, and specifically to the use of databases in computers. Still more particularly, the present disclosure relates to a context-based search for data related to entities described in a graph database.

A database is a collection of data. Examples of database types include relational databases, graph databases, network databases, and object-oriented databases. Each type of database presents data in a non-dynamic manner, in which the data is statically stored.

SUMMARY

In one embodiment of the present invention, a context-based system for searching for data stores related to a set of one or more nodes in a graph database is presented. A graph database storage system contains a graph database comprising multiple graph nodes. A first pointer points from a particular graph node to a particular synthetic context event node in a synthetic context event database. A second pointer points from the particular synthetic context event node in the synthetic context event database to a particular data store in a data structure, such that the first pointer and the second pointer associate the particular data store with the particular entity represented in the graph database via the particular synthetic context event node.

In one embodiment, a processor-implemented method searches for data stores related to a set of one or more nodes in a graph database. A processor points from a particular graph node in a graph database to a particular synthetic context event node in a synthetic context event database. The graph database comprises multiple graph nodes, where each of the multiple graph nodes stores an attribute of a particular entity. Each of the multiple graph nodes is logically coupled to another graph node by an edge, which describes a relationship between entities represented by coupled graph nodes. The synthetic context event database is made up of multiple synthetic context event nodes, where each of the synthetic context event nodes contains a descriptor of the attribute of the particular entity as well as the relationship between the particular entity and another entity represented by another graph node. The processor then points from a particular synthetic context event node in the synthetic context event database to a particular data store in a data structure, such that pointing to the particular data store associates the particular data store with the particular entity represented in the graph database via the particular synthetic context event node.

In one embodiment, a computer program product searches for data stores related to a set of one or more nodes in a graph database. Stored on a computer readable storage medium are first program instructions and second program instructions. The first program instructions are to point from a particular data store in a data structure to a particular synthetic context event node in a synthetic context event database, where the synthetic context event database comprises multiple synthetic context event nodes. The particular synthetic context event node contains a descriptor of an attribute of a particular entity represented by a particular graph node in a graph database, and the particular synthetic context event node further contains a relationship described in an edge between said particular graph node and another graph node in the graph database. The second program instructions are to point from the particular synthetic context event node in the synthetic context event database to the particular graph node in the graph database, such that pointing to the particular synthetic context event node and the particular graph node associates the particular data store with the particular entity represented by the graph node via the particular synthetic context event node.

DETAILED DESCRIPTION

As will be appreciated by one skilled in the art, aspects of the present invention may be embodied as a system, method or computer program product. Accordingly, aspects of the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, micro-code, etc.) or an embodiment combining software and hardware aspects that may all generally be referred to herein as a “circuit,” “module” or “system.” Furthermore, aspects of the present invention may take the form of a computer program product embodied in one or more computer readable medium(s) having computer readable program code embodied thereon.

Any combination of one or more computer readable medium(s) may be utilized. The computer readable medium may be a computer readable signal medium or a computer readable storage medium. A computer readable storage medium may be, for example, but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or any suitable combination of the foregoing. More specific examples (a non-exhaustive list) of the computer readable storage medium would include the following: an electrical connection having one or more wires, a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), an optical fiber, a portable compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing. In the context of this document, a computer readable storage medium may be any tangible medium that can contain, or store a program for use by or in connection with an instruction execution system, apparatus, or device.

A computer readable signal medium may include a propagated data signal with computer readable program code embodied therein, for example, in baseband or as part of a carrier wave. Such a propagated signal may take any of a variety of forms, including, but not limited to, electro-magnetic, optical, or any suitable combination thereof. A computer readable signal medium may be any computer readable medium that is not a computer readable storage medium and that can communicate, propagate, or transport a program for use by or in connection with an instruction execution system, apparatus, or device.

Program code embodied on a computer readable medium may be transmitted using any appropriate medium, including, but not limited to, wireless, wireline, optical fiber cable, RF, etc., or any suitable combination of the foregoing.

Computer program code for carrying out operations for aspects of the present invention may be written in any combination of one or more programming languages, including an object oriented programming language such as Java, Smalltalk, C++ or the like and conventional procedural programming languages, such as the “C” programming language or similar programming languages. The program code may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider).

Aspects of the present invention are described below with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems) and computer program products according to embodiments of the present invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks.

These computer program instructions may also be stored in a computer readable medium that can direct a computer, other programmable data processing apparatus, or other devices to function in a particular manner, such that the instructions stored in the computer readable medium produce an article of manufacture including instructions which implement the function/act specified in the flowchart and/or block diagram block or blocks.

The computer program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other devices to cause a series of operational steps to be performed on the computer, other programmable apparatus or other devices to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide processes for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks.

With reference now to the figures, and in particular to FIG. 1, there is depicted a block diagram of an exemplary system and network that may be utilized by and in the implementation of the present invention. Note that some or all of the exemplary architecture, including both depicted hardware and software, shown for and within computer 102 may be utilized by software deploying server 150 and/or a data storage system 152.

Exemplary computer 102 includes a processor 104 that is coupled to a system bus 106. Processor 104 may utilize one or more processors, each of which has one or more processor cores. A video adapter 108, which drives/supports a display 110, is also coupled to system bus 106. System bus 106 is coupled via a bus bridge 112 to an input/output (I/O) bus 114. An I/O interface 116 is coupled to I/O bus 114. I/O interface 116 affords communication with various I/O devices, including a keyboard 118, a mouse 120, a media tray 122 (which may include storage devices such as CD-ROM drives, multi-media interfaces, etc.), a printer 124, and external USB port(s) 126. While the format of the ports connected to I/O interface 116 may be any known to those skilled in the art of computer architecture, in one embodiment some or all of these ports are universal serial bus (USB) ports.

As depicted, computer 102 is able to communicate with a software deploying server 150, using a network interface 130. Network interface 130 is a hardware network interface, such as a network interface card (NIC), etc. Network 128 may be an external network such as the Internet, or an internal network such as an Ethernet or a virtual private network (VPN).

A hard drive interface 132 is also coupled to system bus 106. Hard drive interface 132 interfaces with a hard drive 134. In one embodiment, hard drive 134 populates a system memory 136, which is also coupled to system bus 106. System memory is defined as a lowest level of volatile memory in computer 102. This volatile memory includes additional higher levels of volatile memory (not shown), including, but not limited to, cache memory, registers and buffers. Data that populates system memory 136 includes computer 102's operating system (OS) 138 and application programs 144.

OS 138 includes a shell 140, for providing transparent user access to resources such as application programs 144. Generally, shell 140 is a program that provides an interpreter and an interface between the user and the operating system. More specifically, shell 140 executes commands that are entered into a command line user interface or from a file. Thus, shell 140, also called a command processor, is generally the highest level of the operating system software hierarchy and serves as a command interpreter. The shell provides a system prompt, interprets commands entered by keyboard, mouse, or other user input media, and sends the interpreted command(s) to the appropriate lower levels of the operating system (e.g., a kernel 142) for processing. Note that while shell 140 is a text-based, line-oriented user interface, the present invention will equally well support other user interface modes, such as graphical, voice, gestural, etc.

As depicted, OS 138 also includes kernel 142, which includes lower levels of functionality for OS 138, including providing essential services required by other parts of OS 138 and application programs 144, including memory management, process and task management, disk management, and mouse and keyboard management.

Application programs 144 include a renderer, shown in exemplary manner as a browser 146. Browser 146 includes program modules and instructions enabling a world wide web (WWW) client (i.e., computer 102) to send and receive network messages to the Internet using hypertext transfer protocol (HTTP) messaging, thus enabling communication with software deploying server 150 and other computer systems.

Application programs 144 in computer 102's system memory (as well as software deploying server 150's system memory) also include a context-based data store locating program (CBDSLP) 148. CBDSLP 148 includes code for implementing the processes described below, including those described in FIGS. 2-3. In one embodiment, computer 102 is able to download CBDSLP 148 from software deploying server 150, including in an on-demand basis, wherein the code in CBDSLP 148 is not downloaded until needed for execution. Note further that, in one embodiment of the present invention, software deploying server 150 performs all of the functions associated with the present invention (including execution of CBDSLP 148), thus freeing computer 102 from having to use its own internal computing resources to execute CBDSLP 148.

The data storage system 152 stores an electronic data structure, which may be business/medical records, audio files, video files, website entries, text files, etc. In one embodiment, computer 102 contains the graph database storage system and the synthetic context event database storage system described and claimed herein, while the data storage system is a same or separate system for storing data stores as described and claimed herein.

Note that the hardware elements depicted in computer 102 are not intended to be exhaustive, but rather are representative to highlight essential components required by the present invention. For instance, computer 102 may include alternate memory storage devices such as magnetic cassettes, digital versatile disks (DVDs), Bernoulli cartridges, and the like. These and other variations are intended to be within the spirit and scope of the present invention.

Note that CBDSLP 148 is able to generate and/or utilize some or all of the databases depicted in the context-based system in FIG. 2.

With reference now to FIG. 2, a novel context-based system 200 for searching for data stores related to an entity described by a set of one or more nodes in a graph database is presented. The context-based system 200 comprises a graph database storage system for storing a graph database 202, a synthetic context event database storage system for storing a synthetic context event database 204, and access to a data storage system for storing a data structure 206. In one embodiment, the graph database storage system and the synthetic context event database storage system are part of computer 102 shown in FIG. 1, while the data storage system is the data storage system 152 depicted in FIG. 1.

The graph database 202 is a schema-less database in which data is organized as a set of nodes (objects) with properties (attributes or values). These nodes are linked to other nodes through edges, which describe the relationship between two nodes. As depicted in FIG. 2, these nodes are shown as graph nodes 208 a-208 n, where “n” is an integer. The graph nodes 208 a-208 n are linked by edges 210 x-210 z, which describe relationships between linked graph nodes. For example, assume that graph node 208 a represents “circulatory diseases” (or persons having a circulatory disease), and graph node 208 b represented “myocardial infarction” (or persons who are having or have had a myocardial infarction). The edge 210 x thus describes the graph node 208 b as being a subset of graph node 208 a.

In another example, assume that graph node 208 b still represents persons who have had a myocardial infarction, and graph node 208 n represents all persons who are morbidly obese, live in a certain city/state/country/geographical region, drink green tea, etc. The edge 210 z would thus describe the persons represented by graph node 208 b as “being morbidly obese”, “a resident of the certain city/state/country/geographical region”, a “drinker of green tea”, etc.

In one embodiment, two or more graph nodes can be clustered into a graph node cluster 212, which includes graph node 208 a and graph node 208 n. This graph node cluster 212 has been predetermined to include all related graph nodes (as indicated by linking edges and/or shared attributes within the graph nodes).

The synthetic context event database 204 is made up of synthetic context event nodes 214 a-214 n (where “n” is an integer). These synthetic context event nodes 214 a-214 n may or may not be interlinked (i.e., logically associated with one another by having shared attributes, etc.). Each of these synthetic context event nodes 214 a-214 n represents a synthetic event (i.e., they are fabricated by consolidating information from different sources which may or may not describe an actual event). In the present invention, each of the synthetic context event nodes 214 a-214 n contains a descriptor of an attribute of a particular entity (i.e., information from one or more of the graph nodes 208 a-208 n) and a relationship between a particular entity and another entity represented by another graph node (i.e., the information found in an edge such as edge 210 x).

The data structure 206 is a database of multiple data stores 216 a-216 n, which may be text documents, hierarchical files, tuples, object oriented database stores, spreadsheet cells, uniform resource locators (URLs), etc.

In one embodiment, the data structure 206 is a database of text documents (represented by one or more of the data stores 216 a-216 n), such as journal articles, webpage articles, electronically-stored business/medical/operational notes, etc.

In one embodiment, the data structure 206 is a database of text, audio, video, multimedia, etc. files (represented by one or more of the data stores 216 a-216 n) that are stored in a hierarchical manner, such as in a tree diagram, a lightweight directory access protocol (LDAP) folder, etc.

In one embodiment, the data structure 206 is a relational database, which is a collection of data items organized through a set of formally described tables. A table is made up of one or more rows, known as “tuples”. Each of the tuples (represented by one or more of the data stores 216 a-216 n) share common attributes, which in the table are described by column headings. Each tuple also includes a key, which may be a primary key or a foreign key. A primary key is an identifier (e.g., a letter, number, symbol, etc.) that is stored in a first data cell of a local tuple. A foreign key is typically identical to the primary key, except that it is stored in a first data cell of a remote tuple, thus allowing the local tuple to be logically linked to the foreign tuple.

In one embodiment, the data structure 206 is an object oriented database, which stores objects (represented by one or more of the data stores 216 a-216 n). As understood by those skilled in the art of computer software, an object contains both attributes, which are data (i.e., integers, strings, real numbers, references to another object, etc.), as well as methods, which are similar to procedures/functions, and which define the behavior of the object. Thus, the object oriented database contains both executable code and data.

In one embodiment, the data structure 206 is a spreadsheet, which is made up of rows and columns of cells (represented by one or more of the data stores 216 a-216 n). Each cell (represented by one or more of the data stores 216 a-216 n) contains numeric or text data, or a formula to calculate a value based on the content of one or more of the other cells in the spreadsheet.

In one embodiment, the data structure 206 is a collection of universal resource locators (URLs) for identifying a webpage, in which each URL (or a collection or URLs) is represented by one or more of the data stores 216 a-216 n.

These described types of data stores are exemplary, and are not to be construed as limiting what types of data stores are found within data structure 206.

Note that the data structure 206 is homogenous in one embodiment, while data structure 206 is heterogeneous in another embodiment. For example, assume in a first example that data structure 206 is a relational database, and all of the data stores 216 a-216 n are tuples. In this first example, data structure 206 is homogenous, since all of the data stores 216 a-216 n are of the same type. However, assume in a second example that data store 216 a is a text document, data store 216 b is an MRI image, data store 216 c is a tuple from a relational database, etc. In this second example, data structure 206 is a heterogeneous data structure, since it contains data stores that are of different formats.

In one embodiment, the synthetic context event database 204 may include filtering logic (i.e., part of CBDSLP 148 shown in FIG. 1), which allows the user to specify what type of data store is to be located. For example, such a filter may request only image files (e.g., an MRI image), or it may request only text files (e.g., journal articles), or it may request only universal resource locators (URLs) to websites, or it may request only tuples from a relational database, or it may request any combination of data stores (i.e., a combination of data stores that are inclusive of some types of data stores and are exclusive of other types of data stores).

As depicted in FIG. 2, a first pointer points to one of the synthetic context event nodes 214 a-214 n, and a second pointer points from one of the synthetic context event nodes 214 a-214 n to one of the data stores 216 a-216 n. For example, assume that graph node 208 b represents persons who have had a myocardial infarction, and information from edge 210 x and/or edge 210 z describes those persons' relationships to entities represented by graph node 208 a and graph node 208 n, respectively. In this example, synthetic context event node 214 a contains the information stored in graph node 208 b as well as the information stored in edge 210 x and/or edge 210 z. In order to associate the synthetic context event node 214 a with graph node 208 b and its edges, a first pointer 218 a points from graph node 208 b to synthetic context event node 214 a.

Similarly, a first pointer 218 b points from graph node cluster 212, which includes graph node 208 a and graph node 208 n, as well as the information in edge 210 y, to a synthetic context event node 214 b. In one embodiment, only the information found in graph node 208 a, graph node 208 n, and edge 210 y are represented in synthetic context event node 214 b. In another embodiment, the information found in graph node 208 a, graph node 208 n, and edge 210 y, as well as the information found in edge 210 x and/or edge 210 z are also represented in synthetic context event node 214 b.

As further depicted in FIG. 2, a second pointer points from a synthetic context event node, which was pointed to by the first pointer, to a particular data store in the data structure, such that the first pointer and the second pointer associate the particular data store with the particular entity represented in the graph database via the particular synthetic context event node. For example, continue to assume that graph node 208 b represents persons who have had a myocardial infarction; that information from edge 210 x and/or edge 210 z describes those persons' relation to entities represented by graph node 208 a and graph node 208 n, respectively; that synthetic context event node 214 a contains the information stored in graph node 208 b as well as the information stored in edge 210 x and/or edge 210 z; and that first pointer 218 a points from graph node 208 b to synthetic context event node 214 a. Second pointer 220 a now points from synthetic content event node 214 a to data store 216 a, ultimately resulting in the linkage of graph node 208 b to data store 216 a via synthetic context event node 214 a.

Second pointer 220 a points to (i.e., identifies and/or retrieves) data store 216 a according to a logical relationship between the synthetic context event node 214 a and the data store 216 a. For example, assume that synthetic context event node 214 a contains entries (i.e., information from graph node 208 b and/or edges 210 x and/or 210 z) that match descriptive data such as a keyword, metadata, context-based mined data, etc. found in data store 216 a. In one embodiment, this descriptive data describes an activity related to the entity described in graph node 208 b. For example, graph node 208 b may describe the person's lifestyle (i.e., smoker, runner, etc.), medical history (i.e., has had a particular medical procedure, other disease, treatment in a particular facility or by a particular doctor, etc.), travel history, etc.

If the first pointer 218 b points from graph node cluster 212 to synthetic context event node 214 b, then second pointer 220 b points to data store 216 c, and/or second pointer 220 e points to data store 216 n, thus associating graph node cluster 212 with data store 216 c and/or data store 216 n.

Note that, in one embodiment, the single synthetic context event node 214 a has a first second pointer 220 c as well as a second second pointer 220 d, which point to different data stores 216 b and 216 c. That is, multiple data stores, which may be of the same (i.e., are all magazine articles, web entries, etc.) or different (i.e., one is a text file, one is a video file, etc.) types of data stores. Thus, the term data store is used to describe any type of stored file (i.e., text, video, etc.).

Thus, as described above and depicted in FIG. 2, a context-based system 200 for searching for data stores related to a set of one or more nodes in a graph database is represented. A graph database storage system (i.e., part of computer 102 shown in FIG. 1) contains a graph database 202 made up of multiple graph nodes 208 a-208 n. Each of the multiple graph nodes 208 a-208 n stores an attribute of a particular entity, and each of the multiple graph nodes 208 a-208 n is logically coupled to another graph node by one or more of the edges 210 x-210 z, where each edge describes a relationship between entities represented by coupled graph nodes.

A first pointer (e.g., first pointer 218 a) points from a particular graph node (e.g., graph node 208 b) to a particular synthetic context event node (e.g., synthetic context event node 214 a) in the synthetic context event database 204. A synthetic context event database storage system (i.e., also part of computer 102 shown in FIG. 1) contains the synthetic context event database 204, which contains multiple synthetic context event nodes 214 a-214 n. Each of the multiple synthetic context event nodes 214 a-214 n contains a descriptor of one or more attributes of the particular entity represented by graph node 208 b, as well as the relationship (e.g., found in edge 210 x) between that particular entity and another entity represented by another graph node (e.g., graph node 208 a).

A second pointer (e.g., second pointer 220 a) points from the particular synthetic context event node 214 a in the synthetic context event database 204 to a particular data store 216 a in a data structure 206. Thus, the first pointer 218 a and the second pointer 220 a associate the particular data store 216 a with the particular entity represented in the graph database (i.e., by graph node 208 b) via the particular synthetic context event node 214 a.

Note that data stores 216 a-216 n within data structure 206 do not merely describe or provide additional detail about the information found in a graph node from the graph database 202 and/or the edges 210 x-210 z that connect various graph nodes. Rather, these data stores 216 a-216 n are data stores that are deemed to be related to a particular graph node by a particular synthetic context event node. That is, a particular data store from data stores 216 a-216 n is deemed to be associated to a particular intermediate synthetic context event node by virtue of the contextual information (i.e., information supplied by one or more graph nodes and/or their edges) found in that particular intermediate synthetic context event node. The data store itself, however, is not merely an expansion of this contextual information, but rather is a data store that describes a study, analysis, evaluation, entity association, etc. of the entity(s) described by the relevant graph node(s). For example, data store 216 a may be a medical journal article that has been associated with synthetic context event node 214 a (e.g., by containing certain keywords, metadata, etc.). This medical journal article does not merely describe the information from graph node 208 b and/or the edges to that graph node 208 b, but rather provides medical details about a particular medical study. These medical details include those not suggested by the information from the graph node 208 b and/or the edges to that graph node 208 b.

For example, in one embodiment, the particular data store (e.g., data store 216 a) describes an activity (i.e., lifestyle, medical activities/history, hobbies, travel history, etc.) related to the particular entity depicted by graph node 208 b.

In another exemplary embodiment, the particular data store (e.g., data store 216 a) describes a set of diagnostic and/or treatment options for medical patients described by graph node 208 b.

In another exemplary embodiment, the particular data store (e.g., data store 216 a) describes a set of financial, legal, technical, etc. reports related to a business entity described by graph node 208 b.

In order to link a particular synthetic context event node to a particular data store, various linkage processes may be utilized. For example, in one embodiment, the second pointer 220 a uses a keyword that is in both the particular synthetic context event node 214 a and the particular data store 216 a to point to the particular data store 216 a. In another exemplary embodiment, the second pointer 220 a uses metadata that is associated with both the particular synthetic context event node 214 a and the particular data store 216 a to point to the particular data store 216 a.

In one embodiment, multiple second pointers (e.g., second pointers 220 a, 220 c and 220 d) point from the particular synthetic context event node 214 a to multiple data stores 216 a, 216 b and 216 c in the data structure 206.

In one embodiment, a first second pointer 220 d from a first synthetic context event node 214 a and a second second pointer 220 b from a second synthetic context event node 214 b point to a same data store 216 c in the data structure 206. That is, a same data store 216 c may be relevant to two synthetic context event nodes, and thus related to two different graph nodes and/or graph node clusters.

In one embodiment, the data structure 206 is a relational database, such that the particular data store (e.g., data store 216 a) is a tuple within the relational database.

In one embodiment, the data structure 206 is a text data structure, such that the particular data store (e.g., data store 216 a) describes a study (i.e., a medical journal article, doctor's notes, engineering notes, financial reports, etc.) about the particular entity represented in the graph database 202.

With reference now to FIG. 3, a high-level flow chart of one or more steps performed by a computer processor to locate data stores related to an entity represented by a set of one or more nodes in a graph database is presented. After initiator block 302, a processor points (e.g., using a first pointer such as first pointer 218 a shown in FIG. 2) from a particular graph node (e.g., graph node 208 b) in a graph database (e.g., graph database 202) to a particular synthetic context event node (e.g., synthetic context event node 214 a) in a synthetic content event database (e.g., synthetic context event database 204 (block 304). The graph database comprises multiple graph nodes, wherein each of the multiple graph nodes stores an attribute of a particular entity that is described by the particular graph node. Each of the multiple graph nodes is logically coupled to another graph node by an edge, which describes a relationship between entities represented by coupled graph nodes.

The synthetic context event database comprises multiple synthetic context event nodes. Each of the multiple synthetic context event nodes contains a descriptor of the attribute of the particular entity as well as the relationship between the particular entity and another entity represented by another graph node in the graph database.

As described in block 306, the processor then points (e.g., using a second pointer such as second pointer 220 a shown in FIG. 2) from the particular synthetic context event node (e.g., synthetic context event node 214 a) in the synthetic context event database to a particular data store (e.g., data store 216 a) in a data structure (e.g., data structure 206). Thus, pointing to the particular synthetic context event node and the particular data store associates the particular data store with the particular entity (which is represented by a graph node in the graph database) via the particular synthetic context event node.

As described in block 308, the identified data store (e.g., data store 216 a) is then retrieved (e.g., for display, printing, etc.) and sent to a computer system, requesting entity, etc. The process ends at terminator block 310.

While the present invention has been described in the context of a graph node searching for a data store, in one embodiment the process works in the other direction. That is, a particular data store can search for a particular graph node. For example, assume that data store 216 a is a medical journal article about a particular disease (e.g., cancer). Continue to assume that, as described above, data store 216 a is linked by second pointer 220 a to synthetic context event node 214 a, which leads a user to graph node 208 b. At this point, a user who initially only knew about the medical journal article represented as data store 216 a also now knows not only about graph node 208 b, but also knows about linked graph nodes 208 a and 208 n. For example, if graph node 208 b represented a particular genetic marker, which may or may not have been mentioned in the medical journal article, and graph nodes 208 a and 208 n represent other genetic markers, then knowing about these related genetic markers (through the use of the processes described herein) allows the user to expand his data store search. In this example, the user is able to traverse from the newly-identified graph node cluster 212 and/or graph node 208 a or graph node 208 n to data store 216 c and/or data store 216 n. That is, the present invention enables the user to identify data store 216 c and/or data store 216 n, through the use of synthetic context event node 214 b, which is pointed to by first pointer 218 b from the graph node cluster 212 and/or graph node 208 a and/or graph node 208 n. Note that data store 216 c and/or data store 216 n may be another medical journal article, a set of medical examination results (e.g., X-rays, MRIs, lab workups, etc.), etc., which may be in any digital format (e.g., PDF, JPEG, MPEG, .doc, etc.). In this example, note that data store 216 n is accessible only via synthetic context event node 214 b, while data store 216 c is accessible via synthetic context event node 214 a or synthetic context event node 214 b.

In another embodiment, knowing about data store 216 a enables the user to also know about data store 216 b and data store 216 c, since synthetic context event node 214 a not only points to data store 216 a but also to data store 216 b and data store 216 c. Thus, the synthetic context event node 214 a, which is defined by the graph database features described above, allows the user to make a direct connection between different data stores within the data structure 206 via the synthetic context event node 214 a, such that data store 216 b and/or data store 216 c can be located and/or retrieved based on the user's awareness of data store 216 a.

As described in the example shown in FIG. 2, data store 216 n is accessible only via synthetic context event node 214 b, while data store 216 c is accessible via synthetic context event node 214 a or synthetic context event node 214 b. If data store 216 a is used to locate additional related data stores within the data structure 206, then data store 216 c can be located directly via the synthetic context event node 214 a. However, in order to locate/retrieve data store 216 n based on awareness of data store 216 a, a pathway through synthetic context event node 214 a must be traversed to the graph database 202, and then returning through the synthetic context event node 214 b in order to locate/retrieve the data store 216 n via the pointers described herein.
